Tourism has the potential to trigger lifelong changes through a transformative experience. However, existing tourists' transformative experience (TE) research has been criticized for lacking the embodied dimensions of transformative experiences leading to fragmented and contradictory views on what and where these experiences take place in the tourism context. Considering these criticisms coupled with the important role of transformative experience, this study systematically examines tourists' transformative experience literature to address the current knowledge gap. Adopting a quantitative systematic literature review approach, this paper aims to outline the research trends of tourists' transformative experiences and provide insights for future research. The findings suggest that more research concerning transformative experiences in tourism has been dedicated to volunteer tourism discourses as the context of volunteering offers a 'once in a lifetime' experience. The findings also point to a dearth of appropriate and comprehensive theoretical frameworks in the tourism context. The current study found that while transformative experiences are reflected in four dimensions of behavioral, psychological, social, and spiritual experiences; socio-psychological transformation experiences dominate. A research framework with future research questions unpacking possible theoretical and methodological directions is further proposed.

旅游业有可能通过变革性的体验引发终生的改变。然而，现有游客的变革性体验 (TE) 研究因缺乏变革性体验的具体维度而受到批评，导致对这些体验在旅游环境中发生的内容和地点产生了支离破碎和矛盾的观点。考虑到这些批评以及变革性体验的重要作用，本研究系统地检查了游客的变革性体验文献，以解决当前的知识差距。本文采用定量系统的文献综述方法，旨在概述游客变革体验的研究趋势，并为未来的研究提供见解。研究结果表明，更多关于旅游变革性体验的研究致力于志愿者旅游话语，因为志愿服务提供了“一生一次”的体验。调查结果还指出，在旅游背景下缺乏适当和全面的理论框架。目前的研究发现，虽然变革性体验体现在行为、心理、社会和精神体验四个维度；社会心理转变经历占主导地位。进一步提出了一个研究框架，其中包含未来的研究问题，揭示了可能的理论和方法论方向。调查结果还指出，在旅游背景下缺乏适当和全面的理论框架。目前的研究发现，虽然变革性体验体现在行为、心理、社会和精神体验四个维度；社会心理转变经历占主导地位。进一步提出了一个研究框架，其中包含未来的研究问题，揭示了可能的理论和方法论方向。调查结果还指出，在旅游背景下缺乏适当和全面的理论框架。目前的研究发现，虽然变革性体验体现在行为、心理、社会和精神体验四个维度；社会心理转变经历占主导地位。进一步提出了一个研究框架，其中包含未来的研究问题，揭示了可能的理论和方法论方向。
